【摘要】：目前平养蛋鸭只能采用家系选育法而不能采用个体选育法,这是因为在平养条件下很难实现蛋鸭与所产蛋的准确对应。蛋鸭家系选育法的主要缺点是复杂,劳动强度大,准确度低,严重影响选种的精度和效率。在平养环境下实现蛋鸭个体选育法的关键在于找到一种智能化无应激的精确识别和标记蛋鸭个体与其所产种蛋的方法。该文以蛋鸭为研究对象,提出了一种新型的平养蛋鸭种蛋智能收集和标记系统设计框架,给出了上位机和下位机的组网拓扑图和逻辑控制算法。该系统采用射频技术和光电传感器技术融合,实现了蛋鸭产蛋个体的准确识别,识别正确率为100%。利用非接触式喷码打印技术将蛋鸭个体编号信息记录在其所产种蛋蛋壳上,解决了蛋鸭个体与所产鸭蛋对应关系的无应激自动记录难题。设计并实现了集种蛋收集和标记于一体的新型集蛋装置。该装置由集蛋区、调整区和喷印区3部分组成。集蛋区采用梯形凹槽结构和EVA海绵弹性触面设计,消除了种蛋在加速滚落过程中积累的动能,种蛋的破损率低于1%。调整区采用滑触式种蛋姿态导向设计,种蛋姿态调整的合格率达到了99.80%,保证了蛋壳长轴截面作为喷印面,使喷印的字符最大程度保持完整性。喷印区采用连续式油墨喷码机完成蛋鸭个体与种蛋对应关系的标记,喷码标识清晰可读合格率为98.2%。该研究可为蛋鸭生产过程中个体产蛋行为分析和种蛋信息的自动收集提供参考。
[Abstract]:At present, laying duck can only adopt family breeding method, but not individual breeding method, which is because it is difficult to realize the exact correspondence between egg duck and egg under the condition of flat raising. The main disadvantages of the breeding method of laying duck are complexity, high labor intensity and low accuracy, which seriously affect the precision and efficiency of selection. The key to realize the individual breeding method of laying duck under the condition of flat raising is to find an intelligent and stress-free method to accurately identify and mark the individual and the eggs they produce. In this paper, a new design framework of intelligent collection and marking system for laying duck breeding is proposed, and the network topology and logic control algorithm of upper computer and lower computer are given. The system uses radio frequency technology and photoelectric sensor technology to realize the accurate identification of egg laying individuals, and the recognition accuracy is 100. The information of individual number of laying duck was recorded on the egg shell by non-contact spray code printing technology, which solved the problem of non-stress automatic recording of the corresponding relationship between individual and duck egg. A new type of egg collecting device is designed and implemented. The device consists of egg collecting area, adjusting area and printing area. The structure of trapezoidal groove and EVA sponge elastic contact surface were used to eliminate the kinetic energy accumulated during the accelerated rolling of the eggs and the damage rate of the eggs was less than 1. The adjustment area is designed by sliding contact attitude orientation, and the qualified rate of egg posture adjustment reaches 99.80, which ensures that the long axis section of egg shell can be used as spray printing surface, and the character of spray printing can be kept intact to the greatest extent. Continuous ink printer was used to mark the relationship between egg duck and egg, and the legible qualification rate was 98.2%. This study can provide reference for the analysis of individual egg laying behavior and the automatic collection of egg breeding information during laying duck production.
